This is a boot animation installer app for my Nexus BIOS boot animation.

Nexus 5, Nexus 7 (both versions), and Nexus 10 are supported.

The difference between models in this app are purely cosmetic. Any animation will work on any device of matching resolution, so it doesn't matter if you install the D821/16GB animation on a D820/32GB. The only thing wrong will be inaccurate information displayed in the boot animation.
